C1 are the faster handicap boats and have previously sailed the same course as F18.
C3 are the slower handicap and sail with the H16/ Dart 18 etc.

Problems do arise with pre-registration but are normally sorted out at actual event registration. It is difficult to comment without seeing the boat type on the pre-registration list. The point of the SCHRS divide is not quoted but I think has been somewhere in the H16 area previously.

Great event. The start of the raid d'houat is 'interesting' with circa 300 cats!!!
